Does Employment Status Matter for Emerging Adult Identity Development and Life Satisfaction? A Two-wave Longitudinal Study.

Late emerging adulthood is pivotal for identity exploration and development and is interrelated with life satisfaction. In the development of identity and life satisfaction, it is important to have a stable employment status that supports the foundation of life. However, the interrelationships among identity, life satisfaction, and employment status in late emerging adulthood are unclear. Using a two-wave longitudinal survey, this study examined identity development and whether the relationship between identity and life satisfaction varies by employment status. Participants included 875 Japanese emerging adults (65.5% women, Mage = 24.74, SDage = 0.44). Multivariate analysis of variance showed that identity synthesis decreased for those who lost their jobs or those who changed from being full-time to part-time employment. Additionally, individuals with full-time employment had higher identity synthesis and lower confusion than those with part-time or no employment. Multi-group path analysis indicated that identity synthesis was positively associated with life satisfaction and confusion was negatively associated, and these relationships did not differ by employment status. These findings suggest that identity development in late emerging adulthood varies by employment status and that the association between identity and life satisfaction may not be moderated by employment status. Overall, this study contributes to elucidating the characteristics of identity development along employment status and its relationship to life satisfaction in late emerging adulthood.

Exploring trauma exposure and post-traumatic stress in university students of different identity statuses in Lithuania and Japan.

Emerging adulthood is the time when identity questions are addressed. It is also a time of excessive stress and risk for mental health problems. Different identity statuses relate to different mental health outcomes. Yet, little research has addressed how identity status is interlinked with trauma exposure and post-traumatic stress reactions, especially in multicultural contexts. The current study aimed to explore whether different traumatic experiences are related to the current identity status of university students aged between 18 and 29 years and investigate to what extent trauma-exposed emerging adults of different identity statuses report symptoms of post-traumatic stress disorder (PTSD) and complex PTSD (CPTSD). In total, 2237 university students from Lithuania (n = 791) and Japan (n = 1345) participated in the current study. Identity profiles were revealed by using the Latent Class Analysis approach. Lithuania and Japan were comparable in terms of identity profiles and structure of PTSD/CPTSD. Trauma-exposed emerging adults reported a higher probability of being in troubled diffusion identity status; students in achievement identity status had a lower probability of CPTSD and lower rates of symptoms of disturbances in self-organization. The diffused identity of emerging adults from Lithuania and Japan is associated with trauma exposure, and positive identity is linked with fewer CPTSD reactions.

Relationship between Personality Traits and Subjective Well-Being in Emerging Adulthood: Moderating Role of Independent and Interdependent Self-Construal.

During emerging adulthood, individuals' subjective well-being declines owing to challenges regarding identity, work, and romantic relationships. Although the relationships among personality traits, self-construal, and well-being have been examined, studies have focused on personal rather than relational subjective well-being. Furthermore, self-construal's moderating effect on the relationship between personality traits and subjective well-being remains unclear. Therefore, this study examined the relationships among the Big-five personality traits and subjective well-being (life satisfaction, happiness, and interdependent happiness) and the moderating effect of self-construal among 1548 Japanese emerging adults (Mage = 22.24, SD = 1.01). Regression analysis indicated that all aspects of subjective well-being were negatively associated with neuroticism and positively associated with extraversion, independent and interdependent self-construal. Further, agreeableness was positively associated with personal and relational well-being. Independent or interdependent self-construal can moderate the relationships between neuroticism, extraversion, and agreeableness and subjective well-being. Overall, these findings provide valuable insights for improving Japanese emerging adults' well-being.

Adolescents' Identity Development Predicts the Transition and the Adjustment to Tertiary Education or Work.

Although identity development is crucial in individuals' psychological adjustment from adolescence to adulthood, little is known about its impact in the transition to tertiary education or work. This study examined whether identity development during high school predicts career choices and adjustment (i.e., engagement) and maladjustment (i.e., burnout) after graduation. A total of 357 Japanese adolescents participated throughout the 3-year period of vocational high school (Mage = 15.75; 62.75% girls). A follow-up assessment, at 18 months after the school-to-tertiary education or school-to-work transitions, was conducted. Higher identity synthesis during high school years predicted entry into tertiary education, while higher identity confusion predicted transition to work. Furthermore, higher identity synthesis during the high school years predicted higher post-graduation academic engagement, and higher levels of identity confusion predicted higher levels of post-graduation academic or work burnout. Overall, this study contributes to the understanding of the role of identity development in adolescence as a valuable asset for predicting the transition and the adjustment to tertiary education or work.

Identity development and online and offline prosocial behaviors among early and middle adolescents.

Research has demonstrated that adolescents of the digital age engage in developmental tasks by interacting with others in both online and offline environments. However, no studies have investigated how adolescents develop their identity, a crucial developmental task, by engaging in online and offline prosocial behaviors. To address this research gap, we examined the role of online and offline prosocial behavior in identity development during adolescence using variable- and person-centered approaches. The participants were 608 individuals in early adolescence (50.2% girls; age range = 12-13 years, Mage = 12.75 years, SD = 0.43) and 594 individuals in middle adolescence (50.3% girls; age range = 15-16 years, Mage = 15.79 years, SD = 0.41) in Japan. They completed questionnaires to measure identity development, online and offline prosocial behavior, and demographic characteristics. The results from the variable-centered approach (i.e., identity dimensions) revealed that both online and offline prosocial behaviors were positively related to commitments and proactive explorations in early and middle adolescence. The findings from the person-centered approach (i.e., identity statuses) demonstrated that early and middle adolescents with higher levels of online prosocial behavior were more likely to show searching moratorium than all other identity statuses, whereas those with higher levels of offline prosocial behavior were more likely to show achievement than troubled diffusion, carefree diffusion, and undifferentiated. Consistent with both variable- and person-centered approaches, these findings highlight that online prosocial behavior can be a new resource for identity development in adolescence. Moreover, the results suggest that online prosocial behaviors lead to identity status in the process of maturing identity and that offline prosocial behavior is necessary to become more mature identity status. Regarding practical implications, educating adolescents on digital media literacy, including supportive behavior in online environments, is crucial to gradually exploring their identity. In addition, for adolescents to develop more mature identity, adults should create in-person environments in which they participate in offline prosocial behavior. The limitations of our findings with respect to the online and offline prosocial behavior scale items are discussed.

Trauma exposure, posttraumatic stress, and identity content valences among Japanese adolescents.

INTRODUCTION: Theorists and a few empirical studies have suggested that traumatic experiences, posttraumatic stress disorder (PTSD), and complex PTSD (CPTSD) may affect identity development. However, existing studies have overlooked how adolescents' traumas are associated with the alignment of their identity with socio-cultural expectations, which is a crucial component of identity development. To address this gap, this study examined the associations of various types of potentially traumatic experiences and PTSD and CPTSD symptoms with the positive and negative valences of identity affected by desirable and undesirable images within socio-cultural contexts. METHODS: A cross-sectional survey of 341 adolescents (44.0% girls; Mage = 14.8, SD = 1.8) was conducted in Japan. RESULTS: Exposure to certain types of potentially traumatic events (e.g., family violence and physical attack) were related to high levels of negative identity elements, whereas none of the types were related to positive identity elements. The results also indicated that CPTSD-specific symptoms of disturbances in self-organization (DSO) were related to high levels of negative identity elements rather than PTSD. CONCLUSIONS: The findings expand upon related research by suggesting that adolescents' exposure to some types of traumatic events (e.g., family violence and physical attack) and posttraumatic DSO symptoms have the potential to disturb the alignment of their identities with socio-cultural expectations.

I was, I am, I will be: Identity and time perspective before and during COVID-19.

The ways in which youth reach a stable identity, a core developmental task of emerging adulthood, are intertwined with their perceptions of the past, present, and future. Additionally, these dynamics are embedded in and are strongly influenced by the socio-historical context and concurrent events, such as COVID-19. This study examines how different groups of emerging adults (university students and workers) engage in identity processes in educational/vocational and interpersonal domains and frame their perspective of time before (N = 299, Mage  = 21.90; 51.4% females) and during the pandemic (N = 497; Mage  = 23.11; 68.2% females). Significant differences in identity processes and time perspective emerged between the two cohorts. Moreover, significant associations between identity and time perspective were found to be similar across different identity domains and cohorts.

Patterns of Personality Development and Psychosocial Functioning in Japanese Adolescents: A Four-Wave Longitudinal Study.

While patterns of adolescent personality development are country-specific, previous studies that have examined them have been limited to the Netherlands and Finland. This study aimed to identify the patterns of personality development and examine the relationship between these patterns and psychosocial functioning among Japanese adolescents. Overall, 618 Japanese adolescents (49.5% girls; 16 years) participated in the annual longitudinal survey from 2013 to 2016. Using latent class growth analysis, the following four patterns of personality development were identified: resilient, over-controlled, vulnerable, and moderate. Although the mean-level changes in the Big Five domains were generally insignificant among the four patterns, the vulnerable pattern showed a progressive increase in conscientiousness, and the moderate pattern showed a decrease in neuroticism and an increase in conscientiousness. Furthermore, multivariate analysis of variance tests indicated that the resilient pattern showed higher subjective well-being and lower psychosocial problems than the other personality patterns; the over-controlled pattern showed higher internalizing problems than the resilient pattern; the vulnerable pattern showed lower subjective well-being and higher internalizing problems than the other patterns; and the moderate pattern scored between the resilient, over-controlled, and vulnerable patterns in both subjective well-being and psychosocial problems. These findings suggest that the vulnerable and moderate patterns, which are immature patterns compared to the resilient and over-controlled ones, showed positive changes to the direction of maturity from middle to late adolescence in Japan.

Profiles of Emotional Separation and Parental Trust from Adolescence to Emerging Adulthood: Age Differences and Associations with Identity and Life Satisfaction.

Youth become psychologically independent by emotionally separating from their parents and simultaneously developing a sense of trust in them. While these relational components have been addressed separately, studies focusing on the change in dynamics of these components are lacking. This study examined profiles of parent-youth relationship quality based on emotional separation and parental trust, age differences in the prevalence of these profiles, and age differences in the associations between the profiles, identity, and life satisfaction. Participants included 14,428 youth living in Japan from five age groups (44.8% girls/women; Mage = 20.6 years; range = 12-25 years). Six profiles were identified: healthy-independent, unhealthy-independent, balanced, moderate/ambivalent, connected, and distant. The connected profile was predominant among early adolescents, while the healthy-independent profile was predominant among late adolescents and early and middle emerging adults. Among all age groups, identity synthesis was the highest in the healthy-independent profile, and life satisfaction was the highest and identity confusion was the lowest in the healthy-independent and connected profiles. These findings indicate that young people navigate the process of becoming independent from their parents by balancing emotional separation and parental trust, and this balance relates to identity development and life satisfaction.

Cross-Cultural Comparison of ICD-11 Adjustment Disorder Prevalence and Its Risk Factors in Japanese and Lithuanian Adolescents.

BACKGROUND: Although there is increasing knowledge about adjustment disorder (AjD) based on the new diagnostic criteria of the International Classification of Diseases (ICD-11), less is known on AjD in adolescents. This study aimed to examine the prevalence of AjD and its risk factors in Japanese and Lithuanian adolescents. METHODS: The cross-sectional study sample comprised 1745 adolescents from Japan (n = 913) and Lithuania (n = 832). AjD was assessed using the Adjustment Disorder New Module-8 (ADNM-8). We compared the prevalence of AjD in Japanese and Lithuanian adolescents. Using multinominal logistic regression analysis, we examined the effects of age, gender, socioeconomic status, and cumulative stressors as societal and cultural factors, resilience as an intrapersonal factor, and loneliness and perceived support as interpersonal factors on adolescent AjD. RESULTS: The prevalence of probable AjD was 11.7% in Lithuanian adolescents and 6.9% in Japanese adolescents. Gender, socioeconomic status, cumulative stressors, resilience, loneliness, and perceived positive social support were each significantly associated with AjD risk. CONCLUSIONS: This cross-cultural comparative study revealed characteristics of the stressors and prevalence of AjD among Japanese and Lithuanian adolescents. In terms of the socio-interpersonal framework model for the stress-response syndrome, sociocultural, intrapersonal, and interpersonal factors were found to be risk factors associated with AjD in adolescents.

Diverse Trajectories of Hikikomori Symptoms During Job Search and the Role of Identity Distress: Three Wave Longitudinal Research.

Objective: Hikikomori, a prolonged form of social withdrawal, has received attention in various research areas. This longitudinal study aimed to identify diverse trajectories of hikikomori symptoms among young Japanese adults engaged in a job search. It also tested whether identity distress, a critical developmental issue, predicts these trajectories while controlling for other risk factors (depressive symptoms, life satisfaction, career expectations, and gender). Methods: A total of 756 third-year Japanese university students (at Time 1, M age = 20.88 years; women: 78.97%) who engaged in job search participated in our three-wave longitudinal survey at six-month intervals. To assess hikikomori symptoms, we used the 25-item Hikikomori Questionnaire. In addition, identity distress was measured using the 10-item Identity Distress Survey. Results: Latent class growth analysis revealed four different trajectories of hikikomori symptoms. Most young adults showed severe levels and escalating hikikomori symptoms over time. In contrast, a small proportion of young adults prevented hikikomori symptoms through the period of job search. Additionally, young adults with more severe levels of identity distress followed trajectories marked by severe hikikomori symptoms after controlling for other risk factors. Conclusion: The present study's findings contribute to developing a primary intervention for hikikomori symptoms by identifying the period of greatest risk. Group-based counseling support for hikikomori from the perspective of identity is recommended.

Direction of associations between personality traits and educational identity processes: Between- and within-person associations.

INTRODUCTION: In adolescence, personality traits and educational identity processes are interwoven. Previous studies have shown that personality traits predict healthy identity commitment and exploration in education. However, the direction of associations between personality traits and an identity process that searches for another identity option (i.e., reconsideration of commitment) is unclear. Furthermore, there is a lack of prospective studies regarding the direction of the association between personality traits and the educational identity process using within-person methods. Therefore, this study examined the direction of these associations. METHODS: Participants of this four-wave longitudinal study comprised 618 Japanese 13-year-old adolescents (53.3% girls). This study involved a 1-year-interval assessment. RESULTS: Cross-lagged panel models (CLPM) indicated that four personality traits (neuroticism, agreeableness, and conscientiousness) predicted three educational identity processes, while reconsideration of commitment predicted two personality traits (i.e., neuroticism and conscientiousness). Random intercept cross-lagged panel models (RI-CLPM) indicated that agreeableness predicted healthy commitment, while commitment predicted agreeableness at within-person level. CONCLUSION: The findings from CLPM suggest that reconsideration of commitment is a significant factor to predict healthy (i.e., conscientiousness) and unhealthy (i.e., neuroticism) personality traits in individual differences. Furthermore, the findings from RI-CLPM suggest that agreeableness may be a key trait in promoting healthy educational identity commitment. Theoretical and practical implications of these findings are discussed.

Daily Identity Processes and Emotions in Young Adulthood: a Five-Day Daily-Diary Method.

The process of exploring and committing to one's identity for the sake of a future-oriented goal is important for young adults' psychosocial functioning. Whereas the relationship between identity process and psychosocial functioning has been examined in long-term longitudinal studies, the short-term relationship between the two at the daily level has not been clarified. This study developed a measure of daily-level identity process and examined their relationship with daily positive and negative emotions, using a five-day daily-diary method. The participants included 721 Japanese young adults aged 18-30 years (54.4% female, Mage = 26.05 years). Results indicated the measure's three-factor structure, including commitment, active exploration, and ruminative exploration. Commitment related positively to life satisfaction and happiness, and negatively related to depression. Active exploration and ruminative exploration indicated negative associations with life satisfaction and happiness, and positive association depression. Latent profile analysis extracted five theoretically meaningful identity profiles at the daily level: foreclosure, moratorium, troubled diffusion, searching moratorium, and carefree diffusion. Logistic regression analyses indicated that troubled diffusion and moratorium, and foreclosure profiles showed lower and higher levels of life satisfaction and happiness, respectively. These results provided evidence of a strong link between young adult's identity processes, profiles, and positive and negative emotions at the everyday level. Implications and suggestions for future research are discussed.

Trajectories in sense of identity and relationship with life satisfaction during adolescence and young adulthood.

Previous research on identity development among adolescents has focused on the processes involved. However, it is unclear how the sense of identity (synthesis and confusion) develops and how it relates to life satisfaction. This study aims to examine the relationship between sense of identity and life satisfaction among Japanese youth living in the urban Kanto, Kansai, and Chubu areas. A total of 5,047 Japanese youth (49.7% female; Time 1 Mage = 17.08 years, range = 12-22 years) in four age groups (early adolescence, middle adolescence, late adolescence, and young adulthood) participated in a three-wave longitudinal study. Latent growth modeling (LGM) analysis revealed that from early to middle adolescence, synthesis continued to be higher than confusion, whereas from late adolescence to young adulthood, confusion tended to be higher than synthesis. The results of the LGM further showed that the change in synthesis was positively related to the change in life satisfaction and the change in confusion was negatively related to it in all age groups. Using latent class growth analysis (LCGA), five identity classes were extracted: high synthesis-low confusion, low synthesis-high confusion, high synthesis-high confusion, low synthesis-low confusion, and moderate synthesis-moderate confusion. LCGA revealed that youth in the high synthesis classes had a higher sense of life satisfaction than did youth in high confusion classes. These findings provide critical insights into trajectories of identity formation and the relationship between identity development and life satisfaction among Japanese youth that can inform future research and programs designed to facilitate their identity formation.

The Satisfaction with Life Scale in Adolescent Samples: Measurement Invariance across 24 Countries and Regions, Age, and Gender.

Measurement of adolescent life satisfaction across cultures has not received much attention in previous empirical research. The present study evaluated measurement invariance of the Satisfaction with Life Scale (SWLS) among adolescents in 24 countries and regions (N = 22,710; age range = 13-19 years; 53% female). A single-factor model with residual covariance between a pair of items tapping past life satisfaction fitted well in 19 countries and regions and showed a partial metric invariance. In a subset of nine countries and regions, partial scalar invariance was supported. Partial metric invariance across all 24 countries and regions was achieved when custom model modifications in five countries and regions were included. Three SWLS items showed evidence of noninvariance across cultures. The measurement model was found to operate similarly across gender and age. Our findings suggest that caution is needed when using the SWLS for measuring life satisfaction among adolescents from different cultures.

Attachment hierarchy in Japan: examining the validity of important people interview in Japanese young adults.

To assess young people's attachment hierarchy, the Important People Interview (IPI) was developed based on Bowlby's conceptualization of ethological behavioral systems. The present study examined the validity of the IPI in a sample of Japanese young adults (N = 472; Mage = 20.34, SD = 1.28; females = 53.81%), because Bowlby's behavioral systems conceptualization has been assumed to be universal. Confirmatory factor analyses revealed agood fit of the IPI model with a Japanese sample. The ranking of the mother in attachment hierarchy correlated positively with young adults' self-esteem, and the ranking of the father correlated negatively with their depressive symptoms. The absence of romantic partner; shorter romantic relationships; living separately with mother, father, and romantic partner; and less frequent meetings with the mother, father, and romantic partner correlated with the higher ranking of friends. When other attachment figures are unavailable, people may flexibly use friends to meet their attachment needs.

Positive and negative valences of identities: Longitudinal associations of identity content valences with adaptive and maladaptive functioning among Japanese young adults.

Erikson's psychosocial developmental theory assumes that valence of one's identity (i.e., identity content valence) defined by positive and negative identity elements is important for understanding patterns of (mal)adaptation. However, previous empirical research on identity and (mal)adaptation has focused on how individuals deal with identity issues (e.g., exploration and commitment), while neglecting identity content valences. In contrast, this study assessed identity content valences in terms of positive and negative identity elements. Theoretically, identity content valences affect (mal)adaptation, whereas individuals' (mal)adaptation influences their identities. Consequently, this study examined reciprocal relationships between identity content valences and adaptation (i.e., prosocial behaviors) and maladaptation (e.g., externalizing symptoms) in a sample of Japanese young adults, including socioculturally relevant indicators of maladaptation (i.e., hikikomori symptoms and suicidal ideation). This study includes 2,313 Japanese young adults who participated in a three-wave longitudinal study. The cross-lagged panel model and random intercept cross-lagged panel model revealed reciprocal relationships between identity content valences and (mal)adaptation at the between-person level. Negative identity elements positively predicted suicidal ideation. Meanwhile, prosocial behaviors positively predicted positive identity elements, whereas hikikomori symptoms and suicidal ideation positively predicted negative identity elements. These relationships were significant only for socioculturally relevant indicators, suggesting the importance of considering sociocultural contexts.

Identity processes and identity content valences: Examining bidirectionality.

Developing identities that are well-aligned with sociocultural expectations is a key psychosocial developmental task for adolescents and emerging adults. Most studies have examined identity development focusing on how individuals develop their identities (identity process), such as identity exploration and commitment. Meanwhile, researchers have emphasized incorporating the what of identity development (identity content) with identity processes to further the understanding of identity development in sociocultural contexts. This study focuses on the positive and negative valences of identity defined by desirable and undesirable images shared in sociocultural contexts. We investigated the bidirectional associations of identity exploration and commitment processes with positive and negative identity elements using longitudinal data over three measurement waves. Participants were 2,313 Japanese emerging adults enrolled in higher education (70.95% women; Mage = 20.43). The cross-lagged panel analysis and random-intercept cross-lagged panel analysis were used to estimate associations at both between- and within-person levels. Results indicated that commitment making negatively predicted negative identity elements, whereas identification with commitment positively predicted positive identity elements. Meanwhile, positive identity elements positively predicted identification with commitment only for participants with low levels of negative identity elements, while negative identity elements negatively predicted commitment making and identification with commitment. These associations were found only at the between-person level. The findings highlight that emerging adults develop identities through close interactions in which they engage in identity exploration and commitment processes, as well as construct identity content valences. Developmental sequences of identity, along with their sociocultural contexts and practical implications, are discussed. (PsycInfo Database Record (c) 2021 APA, all rights reserved).

Association between long-range temporal correlations in intrinsic EEG activity and subjective sense of identity.

The long-range temporal correlation (LRTC) in resting-state intrinsic brain activity is known to be associated with temporal behavioral patterns, including decision making based on internal criteria such as self-knowledge. However, the association between the neuronal LRTC and the subjective sense of identity remains to be explored; in other words, whether our subjective sense of consistent self across time relates to the temporal consistency of neural activity. The present study examined the relationship between the LRTC of resting-state scalp electroencephalography (EEG) and a subjective sense of identity measured by the Erikson Psychosocial Stage Inventory (EPSI). Consistent with our prediction based on previous studies of neuronal-behavioral relationships, the frontocentral alpha LRTC correlated negatively with identity confusion. Moreover, from the descriptive analyses, centroparietal beta LRTC showed negative correlations with identity confusion, and frontal theta LRTC showed positive relationships with identity synthesis. These results suggest that more temporal consistency (reversely, less random noise) in intrinsic brain activity is associated with less confused and better-synthesized identity. Our data provide further evidence that the LRTC of intrinsic brain activity might serve as a noise suppression mechanism at the psychological level.

Emotional separation, parental trust, and psychosocial adjustment in preadolescence and early adolescence.

INTRODUCTION: Emotional separation and parental trust are two fundamental components of parent-adolescent relationships across different cultural contexts. Previous research showed that emotional separation hindered adolescents' psychosocial adjustment, while parental trust benefited it. However, research on preadolescence is lacking. Preadolescence is a crucial period, as theories and findings suggest that too early autonomy around puberty had negative consequences for psychosocial adjustment. This study focused on preadolescence and early adolescence and tested two hypotheses: that emotional separation would be negatively, and parental trust would be positively, associated with psychosocial adjustment, and that this pattern of associations would be more salient in preadolescence than in early adolescence. METHODS: Participants were 856 preadolescent elementary schoolers (49.6% girls; age range 9-12 years, Mage = 10.79, SD = 0.92) and 518 early adolescent junior high schoolers (47.7% girls, age range 12-15 years; Mage = 13.56, SD = 0.98) in Japan, who completed measures of emotional separation, parental trust, and psychosocial adjustment (industry, school adaptation, and daily life behaviors). RESULTS: Emotional separation was negatively associated with reviewing learning contents and doing homework. Parental trust was positively associated with industry, school adaptation, waking up at regular times, and observing rules at school. These relationships did not differ between age groups. CONCLUSIONS: This study highlights that emotional separation has a negative relationship, and parental trust has a positive relationship, with psychosocial adjustment throughout preadolescence and adolescence.
